Sicherheitshinweise

Prüfen Sie vor jedem Start den festen Sitz des Motors und der Luftschraube - insbesondere nach dem Transport, härteren

Landungen sowie Abstürzen. Prüfen Sie ebenfalls vor jedem Start den festen Sitz und die richtige Position der Tragflächen auf

dem Rumpf.

Akku erst einstecken, wenn Ihr Sender eingeschaltet ist und Sie sicher sind, daß das Bedienelement für die Motorsteuerung auf

"AUS" steht.

Im startbereiten Zustand nicht in den Bereich der Luftschraube greifen.

Vorsicht in der Luftschraubendrehebene - auch Zuschauer zur Seite bitten!

Zwischen den Flügen die Motortemperatur durch vorsichtige Fingerprobe prüfen und

vor einem Neustart den Motor ausreichend abkühlen lassen. Die Temperatur ist richtig, wenn Sie den Motor problemlos berühren

können. Insbesondere bei hohen Außentemperaturen kann dieses bis zu 15 Minuten dauern.

Denken Sie immer daran: Niemals auf Personen und Tiere zufliegen.

Conseils de sécurité

Avant chaque décollage, vérifiez la fixation du moteur et de l'hélice, notamment après le transport, après les atterrissages

violents et après un “Crash”. Vérifiez également, avant chaque décollage la fixation ainsi que le positionnement de l’aile par

rapport au fuselage.

Ne branchez l’accu de propulsion que si vous êtes sûr que votre émetteur est allumé et que l’élément de commande moteur est

en position “ARRET”.

Ne mettez pas vos doigts dans l’hélice! Attention à la mise en marche, demandez également aux spectateurs de reculer.

Entre deux vols, vérifiez en posant un doigt dessus, la température du moteur, laissezle refroidir suffisamment avant le prochain

décollage. La température est correcte si vous pouvez maintenir votre doigt ou votre main sur le moteur. Le temps de refroidissement

peut varier jusqu’à 15 minutes s’il fait particulièrement chaud.

Pensez-y toujours: ne volez jamais vers ou au-dessus des personnes ou des animaux.

Safety notes

Before every flight check that the motor and propeller are in place and secure - especially after transporting the model, and after

hard landings and crashes. Check also that the wing is correctly located and firmly secured on the fuselage before each flight.

Don’t plug in the battery until you have switched on the transmitter, and you are sure that the motor control on the transmitter is set

to “OFF”.

When the model is switched on, ready to fly, take care not to touch the propeller. Keep well clear of the propeller disc too, and ask

spectators to stay back.

Allow the motor to cool down after each flight. You can check this by carefully touching the motor case with your finger. The

temperature is correct when you can hold your finger on the case without any problem. On hot days this may take up to 15

minutes.

Please keep in mind at all times: don’t fly towards people or animals.

Note di sicurezza

Prima di ogni decollo controllare che il motore e la eliche siano fissati stabilmente - specialmente dopo il trasporto, atterraggi duri

e se il modello è precipitato. Controllare prima del decollo anche il fissaggio e la posizione corretta delle ali sulla fusoliera.

Collegare la batteria solo quando la radio è inserita ed il comando del motore è sicuramente in posizione ”SPENTO”.

Prima del decollo non avvicinarsi al campo di rotazione della eliche. Attenzione alla eliche in movimento - pregare che eventuali

spettatori si portino alla dovuta distanza di sicurezza!

Tra un volo e l’altro controllare cautamente con le dita la temperatura del motore e farli raffreddare sufficientemente prima di ogni

nuovo decollo. La temperatura è giusta se si possono toccare senza problemi. Specialmente con una temperatura esterna alta

questo può durare fino a 15 minuti.

Fare attenzione: Non volare mai nella direzione di persone ed animali.

Advertencias de seguridad

Compruebe antes de cada despegue que el motor y la hélice estén fuertemente sujetados, sobretodo después de haberlo

transportado, de aterrizajes más fuertes así como después de una caída. Compruebe igualmente antes de cada despegue que

las alas estén bien sujetas y bien colocadas en el fuselaje.

Conectar la batería, cuando la emisora esté encendida y Usted esté seguro que el elemento de mando para el motor esté en

”OFF”.

No meter la mano en la zona inmediata a la hélice cuando el avión esté a punto de despegar. ¡Cuidado con la zona de la hélice!

¡Pedir a los espectadores que se aparten!

Entre los vuelos hay que comprobar cuidadosamente la temperatura del motor con el dedo y dejar que el motor se enfríe antes

de volver a despegar. La temperatura es correcta, si puede tocar el motor sin problemas. Sobretodo en el caso de temperaturas

del ambiente muy altas, esto puede tardar unos 15 minutos.

Recuerde: No volar nunca hacía personas o animales.

EasyGlider PRO + electric BlueEdition

Examine your kit carefully!

MULTIPLEX model kits are subject to constant quality checks throughout the production process, and we sincerely hope that you are

completely satisfied with the contents of your kit. However, we would ask you to check all the parts (referring to the Parts List) before

you start construction, as we cannot exchange components which you have already worked on. If you find any part is not

acceptable for any reason, we will gladly correct the defect or replace the item in question once we have inspected it. Please send the

part to our Model Department, being sure to include the purchase receipt and a brief description of the fault.

We are constantly working on improving our models, and for this reason we must reserve the right to change the kit contents in terms

of shape or dimensions of parts, technology, materials and fittings, without prior notification. Please understand that we cannot

entertain claims against us if the kit contents do not agree in every respect with the instructions and the illustrations.

Caution!

Radio-controlled models, and especially model aircraft, are by no means playthings. Building and operating them safely

requires a certain level of technical competence and manual skill, together with discipline and a responsible attitude at the

flying field. Errors and carelessness in building and flying the model can result in serious personal injury and damage to

property. Since we, as manufacturers, have no control over the construction, maintenance and operation of our products, we

are obliged to take this opportunity to point out these hazards and to emphasise your personal responsibility.

Additional items required for the EasyGlider PRO:

Adhesive:

Use medium-viscosity cyano-acrylate glue (“cyano” - not styrofoam cyano) Zacki ELAPOR # 85 2727 for this model.

Epoxy adhesives produce what initially appears to be a sound joint, but the bond is only superficial, and the hard resin breaks away

from the parts under load. Hot-melt glue (from a glue gun) is a useful alternative adhesive.

Important note

This model is not made of styrofoam™, and it is not

possible to glue the material using white glue or epoxy.

Please be sure to use cyano-acrylate glue exclusively,

preferably in conjunction with cyano activator (”kicker”).

We recommend medium-viscosity (thick) cyano. This is the

procedure with Elapor®: spray cyano activator on one face

of the joint; allow it to air-dry for around two minutes until

the surface appears to be “dry”, then apply cyano adhesive

to the other face. Join the parts, and immediately position

them accurately.

Please take care when handling cyano-acrylate adhesives.

These materials harden in seconds, so don’t get them on

your fingers or other parts of the body. We strongly

recommend the use of goggles to protect your eyes.

Keep the adhesive out of the reach of children!

1. Before starting construction

Please check the contents of your kit before you start

construction. You will find Figs. 1 + 2 and the Parts List helpful

here.

Completing the fuselage and tail panels

2. Preparing the “snakes”

Check the length of the elevator snake sleeves 43 and 45, and

shorten them if necessary.

43 3 / 2 Ø x 785 mm

45 2 / 1 Ø x 850 mm

Steel 41 0.8 Ø x 875 mm, insert!

Repeat the procedure with the rudder snake sleeves 44 and

46.

44 3 / 2 Ø x 785 mm

46 2 / 1 Ø x 850 mm

Steel 42 0.8 Ø x 875 mm, insert!

Aerial sleeve 47 3/2 Ø x 785 mm (shorten if

necessary)

3. Installing the snakes in the fuselage shells

Important: the fuselage tail boom is considerably strengthened

and stiffened by the addition of the snake outer sleeves 43 and

44, which must be glued full-length to the shells in order to

obtain the full effect. The same applies to the aerial sleeve 47.

Check that the snakes operate smoothly and freely, and take

care not to allow glue to run into the outer sleeves.

Left-hand fuselage shell:

Install the complete elevator snake (wire rod length = 875 mm)

in the left-hand fuselage shell; the pre-formed end should be at

the front (servo end).

Fig. 3

Position the snake outer sleeve 43 flush at the front of the

fuselage shell, as shown in Fig. 4. Lay the shell down flat and

run cyano along the whole length of the outer sleeve 43 and

the channel in the fuselage to glue the parts together strongly.

Fig. 5

Right-hand fuselage shell:

Install the complete rudder snake (wire rod length = 875mm) in

the right-hand fuselage shell. The pre-formed end should be at

the front (servo end).

Fig. 6

Position the snake outer sleeve 44 flush at the front of the

fuselage shell, as shown in Fig. 7. Lay the shell down flat (note

the locating spigot; place the fuselage shell over the corner of

the table) and run cyano along the whole length of the outer

sleeve 44 and the channel in the fuselage to glue the parts

together strongly.

Fig. 8

4. Installing the aerial sleeve

Trial-fit the aerial sleeve 47, cut it to length and glue it in the

right-hand fuselage shell - taking care not to bend or distort the

moulding.

Fig. 9

5. Installing the tow-hook

Glider version: glue the towhook 32 in the moulded recess in

the fuselage shell 4.

Fig. 9

6. Installing the motor mount

Glue the motor mount 34 in the right-hand fuselage shell, and

wipe away any adhesive which is squeezed out. The exposed

face of the motor mount will later be glued when the shells are

joined; take care to keep adhesive off this area. Note that the

motor mount should also be installed in the glider version, as it

adds considerable strength.

Fig. 10

7. Installing the servos in the fuselage shells

Set the servos to “neutral” (centre) from the transmitter, and fit

them in the moulded recesses in the left and right fuselage

shells, as shown in Fig. 11. If you are using different servos,

you may have to trim the recesses slightly to obtain a close fit.

Lay the servo leads in the channel, running from bottom to top,

and tape them in place. Apply a drop of cyano to the servo lugs to

attach them to the foam material. Connect the pre-formed ends

of the wire pushrods to the servo output arms, and push the arms

onto the servos at an angle of 90° to the servo sides (don’t forget

to fit the servo output screws). Glue the plastic latch catches 22

in both fuselage sides as shown. Glue the extension leads in the

cable holders 36, positioning the ends flush as shown in the de-

tail drawing. Glue the cable holders 36 in the moulded recesses

in both fuselage sides, pushing them in as far as they will go.

Deploy the leads carefully and glue the fore-and-aft formers 37 in

place.

Fig. 11

8. Joining the fuselage shells

The most suitable adhesive for this stage is thick cyano-acrylate,

used in conjunction with activator.

Caution: for the tuning version the balance weights 2 x 33 should

first be glued in the recesses at the tail, as shown in Fig. 12.

The first step is to check “dry” (no glue) that the fuselage shells 3

+ 4 fit together accurately; it may be necessary to carry out minor

trimming.

Spray cyano activator on the joint surfaces of the fuselage shell 4

and leave it to air-dry for about two minutes.

Apply cyano adhesive to the joint surfaces of the fuselage shell

3, then join the parts carefully, taking care to align them accurately

and immediately. Note that the fuselage joint line must be perfectly

straight - no bends allowed!

Fig. 12

9. Installing the rudder hinge

Glue the rudder hinge 31 in the tail end of the fuselage using a

small amount of cyano. Take great care that no glue gets onto the

hinge pivot axis.

Fig. 13

Use a sharp balsa knife to cut a central slot for the rudder hinge

31 in the leading edge of the rudder. Take care: injury hazard!

Extend the slot in the rudder 5 downward by about 3 to 4 mm, as

this makes it easier to install the rudder and tailplane at a later

stage.

Fig. 14

10. Attaching the horn to the rudder

Use a pair of side-cutters to cut down the projecting spigot of the

rudder horn 24 to a length of about 2 mm. Insert the swivel pushrod

connector 25 in the second hole from the inside of the rudder

horn 24, and secure it with the washer 26 and nut 27. Caution:

note the orientation of the swivel connector! Tighten the nut very

carefully so that the barrel swivels smoothly: it should not wobble,

but must not jam. Apply a tiny drop of cyano to the nut (on the tip

of a pin) when you are satisfied. Fit the grubscrew 28 in the

threaded hole in the swivel pushrod connector 25 using the allen

key 29 provided. Apply cyano activator to the moulded recess in

the rudder, then glue the rudder horn 24 in the recess, with the

row of holes facing the hinge pivot axis.

Fig. 15

11. Freeing the elevator and rudder

Cut a 1 mm slot at each end of the elevator, which is attached to

the tailplane 12. Move the rudder and elevator to and fro repeatedly

in order to make the hinges free-moving - do not separate the

control surfaces!

Fig. 16

12. Attaching the horn to the elevator

Insert the swivel pushrod connector 25 in the outermost hole in

the elevator horn 24, and secure it with the washer 26 and the nut

27. Caution: note the orientation of the swivel connector! Tighten

the nut very carefully so that the barrel swivels smoothly: it should

not wobble, but must not jam. Apply a tiny drop of cyano to the

nut (on the tip of a pin) when you are satisfied. Fit the grubscrew

28 in the threaded hole in the swivel pushrod connector 25 using

the allen key 29 provided.

Apply cyano activator to the moulded recess in the elevator, then

glue the horn 24 in the recess, with the row of holes facing the

hinge pivot axis.

Fig. 17

13. Gluing the fin to the tailplane

Glue the fin 13 to the tailplane 12, setting it exactly at 90°.

Check this with a tool such as a setsquare.

Fig. 18

14. Gluing the tail assembly to the fuselage

Position the tail assembly on the fuselage “dry” (no glue), and

check that the parts fit correctly: first insert the hinge 31 in the

rudder 13, then slide the assembly forward onto the fuselage.

Check in particular that the tailplane 12 is a snug fit on the fuselage,

without any gaps, and lies parallel to the wing saddle at the front

of the fuselage. You can check this by laying the GRP wing joiner

40 on the wing saddle, fixing it in place exactly at right-angles to

the fuselage centreline using paper masking tape. Now sight along

the fuselage from the nose, and align the tailplane with the wing

joiner. When you are confident that the parts can be positioned

correctly, the tail assembly can be glued to the fuselage

permanently. Check once more for correct alignment and a close

fit before leaving the glue to harden. A little extra care at this stage

is well worthwhile, as it avoids long-term disappointment in a model

which refuses to fly straight.

15. Securing the rudder and elevator pushrods

Slip the wire pushrods 41 and 42 through the swivel pushrod

connectors 25, set the servos and control surfaces to neutral

(centre), and tighten the socket-head grubscrews 28 in the

connectors to secure the pushrods.

Figs. 19 + 20

Completing the wings

16. Freeing the ailerons

Cut a 1 mm slot at each end of the ailerons, which are attached to

the wing panels 8 and 9. Move the ailerons to and fro repeatedly

in order to make the hinges free-moving - do not separate the

control surfaces!

Fig. 21

17. Attaching the horns to the ailerons

Insert the swivel pushrod connectors 25 in the outermost holes in

the aileron horns 24, and secure them with the washers 26 and

the nuts 27.

Caution: be sure to produce a handed pair (different left and right)!

Tighten the nuts very carefully so that the barrels swivel smoothly:

they should not wobble, but must not jam. Apply a tiny drop of

cyano to the nuts (on the tip of a pin) when you are satisfied. Fit

the grubscrews 28 in the threaded holes in the swivel pushrod

connectors 25 using the allen key 29 provided.

Apply cyano activator to the moulded recesses in the ailerons,

then glue the horns 24 in the recesses, with the row of holes

facing the hinge pivot axis.

Fig. 22

18. Installing the aileron servos

Set the servos to “neutral” (centre) from the transmitter, and fit

the output arms on the servos at 90° to the case sides - 1 x left

and 1 x right (mirror-image pair).

Trial-fit the servos in the moulded recesses in the wing panels 8

and 9: you may need to carry out minor adjustments to suit the

type of servo you are using. Apply a drop of hot-melt glue to each

slot in the wings for the servo mounting lugs, and immediately

press the servos into the recesses; apply an extra drop of glue if

necessary.

Fig. 23

19. Installing the aileron pushrods

Connect the pre-formed end of the steel pushrods 30 to the

outermost hole in the servo output arms, and slip the plain end

through the swivel pushrod connectors 25. Set the ailerons and

servos to neutral, and tighten the grubscrews 28 to secure the

pushrods.

Fig. 23

20. Deploying the aileron servo leads

Lay each servo lead in a curve running towards the wing joiner

channel, and extend it with a 400 mm extension lead: the leads

can either be soldered together or connected using the standard

plug and socket. You will find a notch in each of the spar covers

10 and 11 designed to accommodate the connectors. Now deploy

the extension leads in a straight line along the front face of the

spar channel, standing on edge.

The servo leads must project from the underside of the wing roots

by 60 mm on the left and 75 mm on the right, as this makes it

possible to connect them to the extension leads glued in the cable

holders 36. The remainder of the extension leads can be stowed

in the channel and secured.

Figs. 23 + 24

21. Installing the spar covers

Carefully trial-fit the spar covers 10 and 11 in the wing panels 8

and 9. When you are confident that the covers are a close fit, and

can be installed flush with the wing surface, they can be glued in

place permanently using cyano. Ensure in particular that no

adhesive gets onto those surfaces of the wings into which the

GRP wing joiner 40 will be inserted later. Please don’t fit the wing

joiner 40 in the wings until you are certain that there is no active

adhesive inside the channels. The best way to ensure this is to

spray activator inside and wait for about five minutes. If you neglect

this warning, you may find that you can never separate the wing

panels again.

Deploy the servo leads in the channel in the spar covers, and

secure them with a little glue (hot-melt adhesive or contact

cement). Don’t use cyano for this, as it tends to make the cable

insulation brittle.

Fig. 23

22. Checking the wing joiner system

The model can now be assembled using the GRP wing joiner 40:

slide the wing panels onto the joiner until they are 5 cm short of

the fuselage on each side, then connect the plugs on the aileron

extension leads to the sockets installed in the fuselage. Slide the

wings closer to the fuselage, and you will find that the connected

leads help to locate them properly. Finally push the wings into the

fuselage on both sides.

Check that the wing panels 8 and 9 are a snug fit (no gaps) where

they meet the fuselage. If they are excessively tight, carefully

compress the edges of the wing root where they enter the fuselage

recess. Note: the wing panels should not be glued to the

fuselage. This enables you to remove the wings to make the

model easier to transport.

Fig. 25

23. Installing the canopy latch lugs

First glue the canopy former 35 in the underside of the canopy 7,

then push the two latch tongues 23 through the former, and set

them flush. Apply thick cyano to the serrated edges - no activator

in this case! - then insert the latch tongues in the slots in the

canopy. Immediately fit the canopy on the fuselage and allow the

latch tongues to engage in the latch catches 22. Check the position

of the canopy on the fuselage without delay, then wait about one

minute before cautiously re-opening the canopy. Spray activator

on the glued joints between the latch tongues and the canopy

former 35.

Fig. 26

24. General note on the receiving system installation

The remaining airborne equipment can now be installed in the

cabin area. Before you fit the receiver battery permanently it is

important to check the model’s Centre of Gravity (CG); you can

often correct the balance point at this stage by shifting the batteries.

Velcro tape (hook tape 20 + loop tape 21) is supplied for securing

the receiving system components, but please note that the

adhesive layer on the tape is not sufficient for this application, so

apply cyano to reinforce the joints.

In both versions of the aeroplane the receiver should be installed

aft of the servos, again using Velcro tape. Thread the aerial wire

(attached to the receiver) into the plastic sleeve 47, which has

already been installed. The easy way to do this is to file a length

of steel rod to a point, then slip it through the sleeve 47 from the

tail end. Push the point into the end of the aerial insulation and

apply a drop of cyano to the joint. You can then pull the aerial

through the sleeve from the tail end.

The model is designed for the installation of an MPX aero-tow

release, # 72 3470; the mechanism is simply glued in the glider

nose 5. A short length of snake outer sleeve runs from the release

unit towards the tow release servo, passing through the centre of

the battery pack as shown. The linkage takes the form of a length

of 1.2 mm Ø steel rod.

Fig. 27

25. Motor + receiving system installation in the electric-

powered version

Our recommended components have been thoroughly tested, and

are well matched to each other.

If you wish to use different units, especially if they take the form of

a more powerful motor, then it is your responsibility to ensure that

the airframe is “up to the job”.

Install the motor and tighten all screws thoroughly. Deploy the

power cables in such a way that they cannot possibly foul any of

the motor’s moving parts. Tape the wires to the fuselage.

Fig. 28

The speed controller can be attached to the fuselage side adjacent

to the receiver, using Velcro tape.

The intended location of the flight battery is the space aft of the

receiver. The battery should be positioned in such a way that little

or no ballast is required to balance the completed model. Secure

the battery with Velcro tape in the usual way.

Now complete all the receiving system connections as described

in the instructions supplied with your radio control system. Check

that all the cables are secured well, but are not under strain or

tension.

Fit the propeller driver on the motor output shaft. Allow about 1

mm clearance between the rear face of the driver and the fuselage.

Attach the propeller blades to the propeller driver, and tighten the

pivot screws fully, but not excessively. The blades must be able

to swing down under their own weight when you hold the model’s

nose up.

Switch the transmitter on, connect the flight battery to the speed

controller, and the controller to the receiver. The controller you

are using must feature a BEC (Battery Eliminator Circuit) system,

i.e. the receiver draws power from the flight battery.

Switch the motor on briefly, and check the direction of rotation of

the propeller. When test-running the power system remove all

light, loose objects behind the model, and hold it really firmly.

Caution: even small motors and propellers represent a

serious injury hazard!

26. Setting the control surface travels

The control surface travels must be correct, otherwise the model

will not respond harmoniously to the controls. All travels are

measured at the widest point of the control surface concerned.

Elevator

up - stick back (towards you) - approx. + 8-10mm

down - stick forward (away from you) - approx. - 8-10mm

Rudder left and right approx.15-20mm

each way

Ailerons

up approx. + 15 mm

down approx. - 6 mm

Spoilers - both ailerons up approx. + 20 mm

Spoiler mixer (elevator trim compensation)

approx. - 4 mm

Fig. 29

The “Spoiler” function is designed to shorten the landing approach

by deflecting both ailerons up simultaneously. At the same time

the appropriate down-elevator trim is mixed in, so that the model

maintains a stable attitude. This function can only be implemented

if your radio control system features suitable mixer facilities.

Please refer to the instructions supplied with your RC system for

details of this.

Note: when you apply a right-aileron command, the right-hand

aileron - as seen from the tail, looking forward - must deflect up.

If you cannot set the stated control surface travels using your

radio control system’s adjustment facilities, you may need to re-

install the swivel pushrod connector in a different hole in the horn.

27. Gilding the lily - applying the decals

The kit is supplied with a multi-colour decal sheet, part 2. Cut out

the individual name placards and emblems and apply them to the

model in the positions shown in the kit box illustration, or in another

arrangement which you find pleasing.

28. Balancing the model

Like every other aircraft, your EasyGlider PRO must be balanced

at a particular point if it is to fly efficiently and stably. Assemble

the model completely, ready to fly. Corrections are possible by

altering the position of the receiver battery or the flight pack. If

this is still not sufficient, add nose ballast or tail ballast until the

model balances at the stated point.

The Centre of Gravity should be at a point 70 mm back from the

leading edge of the wing, measured where the wings meet the

fuselage. Mark this point on the underside of the wing roots with

a waterproof felt-tip pen. Support the model at the marked points

on two fingertips, and the aeroplane should balance level. Make

any adjustments required, and mark the location of the airborne

components once you have found the correct position in the

fuselage, so that you can be sure always to replace the battery in

the same position.

Fig. 30

29. Preparing for the first flight

For the first flight wait for a day with as little breeze as possible.

The early evening is often a good time.

If this is your first model aircraft, your next step is to ask an

experienced model pilot to help you, as things usually do not go

well if you try to manage on your own. Your local model flying club

should be able to help you find someone, or - failing that - your

nearest model shop may be able to assist you. Our flight simulator

for the PC can also provide valuable experience prior to your

“first real steps” in model flying.

You can download the simulator at no charge from our website

www.multiplex-rc.de. You will also need the matching interface

cable for your MPX transmitter; this is available from model shops

under Order No. # 8 5153.Be sure to carry out a range check

before the first flight.

Just before the flight, charge up the transmitter battery and the

flight pack (or receiver battery) using the recommended

procedures. Ensure that “your” channel is not already in use before

you switch on the transmitter.

Ask your assistant to walk away from the model, holding the

transmitter. The aerial should be fitted but completely collapsed.

Your assistant should operate one of the functions constantly while

you watch the servos. The non-controlled servo should stay

motionless up to a range of about 60 m, and the controlled one

should follow the stick movements smoothly and without any delay.

Please note that this check can only give reliable results if the

radio band is clear of interference, and if no other radio control

transmitters are in use - even on different channels. If the range

check is successful, repeat it with the motor running (EasyGlider

Electric only). There should be no more than a very slight reduction

in effective radio range with the motor turning.

If you are not sure about anything, please don’t risk a flight. Send

the whole system (including battery, switch harness and servos)

to the Service Department of your RC system manufacturer and

ask them to check it.

The first flight ...

Glider:

A test-glide from shoulder level, directly into wind, will give you an

approximate idea of the model’s “trim”, i.e. whether it is set up

correctly, or whether the control surfaces or transmitter trims need

to be adjusted. If the model swings away to one side, move the

rudder trim slightly in the opposite direction. If the model banks -

one wing lower than the other - apply slight aileron trim correction.

Hand-towing

This is the classic method of launching a glider to height. Attached

to a suitable length of towline, the model is pulled up by your

assistant running into wind; the glider will rise up the line in a

similar fashion to a kite. The towline first needs to be prepared as

follows: tie the towring and a pennant to the “model” end of the

line. The ring is engaged on the towhook 32, the towline unwound

and your assistant (launcher) takes the free end and walks upwind

until the line is taut. The model should be held under gentle tension

before it is released. The launcher watches the model (over his

shoulder), adjusting his pace to maintain a steady rate of climb.

Take care not to overstress the model during the launch; this is a

particular danger in a fairly strong wind.

Bungee launching

This is the easiest method of launching a glider of this size, as no

assistant is needed, and launch heights of around 100 m are

easily achieved. From this altitude quite long flying times can be

achieved, and they will be even longer if you manage to contact a

thermal, although this does depend on the prevailing weather.

Thermal flying

Making the best use of flat field thermals is not particularly easy,

and calls for considerable skill and experience. Areas of rising air

are harder to detect and recognise at a flat field, because they

tend to occur at higher altitude than at the hillside, where it is

often possible to find lift while the model is cruising along the

edge of the slope and then circle away in it. A thermal at a flat

field which occurs directly overhead is very hard to recognise,

and to exploit it to the full requires a highly skilled pilot. For this

reason it is always best to go thermal seeking off to one side of

where you are standing.

You will recognise thermal contact by the glider’s behaviour. Good

thermals are obvious because the model will climb strongly, but

weak thermals take a practised eye to detect, and you will need a

lot of skill to make use of them. With a little practice you will be

able to recognise likely trigger points for thermals in the local

landscape. The ground warms up in the sun’s heat, but heat

absorption varies according to the type of terrain and the angle of

the sun’s rays. The air over the warmer ground becomes warmer

in turn, and the mass of warm air flows along close to the ground,

driven by the breeze. Strong winds usually prevent thermal build-

up. Any obstruction - a shrub or tree, a fence, the edge of a wood,

a hill, a passing car, even your own model on the landing approach

- may cause this warm air to leave the ground and rise. Imagine a

drop of water on the ceiling, wandering around aimlessly, and

initially staying stuck to the ceiling. If it strikes an obstruction it will

fall on your head. A triggered thermal can be thought of as the

opposite of the drop of water.

The most obvious thermal triggers include sharply defined snow

fields on mountain slopes. The air above the snow field is cooled,

and flows downhill; at the edge of the snow field, part-way down

the valley, the cool air meets warm air flowing gently uphill, and

pushes it up and away as if cut off by a knife. The result is an

extremely powerful but bumpy thermal bubble. Your task is to

locate the rising warm air and centre your model in it. You will

need to control the glider constantly to keep it centred, as you

can expect the most rapid climb rate in the core of the thermal.

Once again, this technique does demand some skill.

To avoid losing sight of the machine be sure to leave the thermal

in good time. Remember that a glider is always easier to see

under a cloud than against a clear blue sky. If you have to lose

height in a hurry, do bear the following in mind:

The structural strength of the EasyGlider PRO is very great for

this class of model, but it is not infinite. If you attempt to destroy

the model forcibly, please don’t expect any sympathy or

compensation from us.

Flying at the slope

Ridge soaring is an extremely attractive form of model flying.

Soaring for hours on end in slope lift, without needing any outside

aid for launching, must be one of the finest of modelling

experiences. But to “milk” a thermal to the limits of vision, bring it

down again in a continuous series of aerobatic manoeuvres, and

then repeat the whole show - that must surely be the last word in

model flying.

But take care - there are dangers for your model lurking at the

slope. Firstly, in most cases landing is much more difficult than at

a flat field site. It is usually necessary to land in the lee of the hill

where the air is turbulent; this calls for concentration and a high-

speed approach with last-minute airbrake extension. A landing

on the slope face, i.e. right in the slope lift, is even more difficult.

Here the trick is to approach slightly downwind, up the slope, and

flare at exactly the right moment, just before touch-down.

Aero-towing

An ideal combination for learning to aero-tow, and for actual aero-

towing, is a Mentor and an EasyGlider PRO. If you wish to take-

off from grass, you will need a fairly powerful motor in the Magi-

ster, e.g. a brushless external rotor type (generally known as an

“outrunner”) with around 300 Watts of power.

For the tow you require a 20 m length of braided cable of 1 to 1.5

mm Ø. Tie a loop of 0.5 mm Ø nylon line (weak link) at the end,

and connect it to the aero-tow release (# 72 3470) fitted to the

EasyGlider PRO.

Fig. 27

Check that the towline is resting on top of the Mentor’s tailplane.

The tug now rolls forward until the towline is taut, and only then

should the tug’s pilot apply full-throttle. Both aeroplanes

accelerate: the tug stays on the ground initially, while the glider

lifts off, but the glider pilot keeps his model flying low above the

ground, directly in the wake of the tug; the tug can now lift off

safely. The two models should be kept climbing steadily, even

through turns. Avoid flying directly over your heads during the

first few attempts at aero-towing, as it is difficult to detect the

models’ attitudes from this angle. To drop the tow cease climbing,

bring the two aeroplanes to straight and level flight, then close

the throttle on the tug and operate the tow-release on the glider.

Electric flying

With the electric version - the EasyGlider Electric - you have the

optimum level of autonomy and independence. You can fly from

a flat field and carry out about four climbs to a sensible gliding

height from a single battery charge. At the slope you can also

keep the electric power system as a “lifebelt”, i.e. you only use

the motor to “keep afloat”, and avoid landing out, i.e. landing at

the bottom of the slope when the lift fails.

Flight performance

What is meant by a glider’s performance?

The two most important parameters are sinking speed and glide

angle. Sinking speed is a measure of the vertical height lost per

second relative to the surrounding air. The sinking speed is

primarily determined by the wing loading (weight relative to wing

area). Here the EasyGlider PRO offers a really excellent

performance - much better than conventional models - as its wing

loading is so low (only around 17 g / dm²). This means that only

slight thermal assistance is necessary (warm air rising) to cause

the model to gain height. Wing loading is also the main factor in

determining the model’s airspeed - the lower the loading, the

slower the model. Low airspeed means that the model can be

turned extremely tightly, and this is also advantageous when ther-

mal flying, as areas of lift are usually very small when close to the

ground.

The glider’s low airspeed also benefits you considerably if you

are a beginner, as you have more time to think, and the model is

more likely to “excuse” a mistake at the controls.

However, there’s always a down-side:

The other important parameter in glider performance is the glide

angle. This is stated as a ratio, i.e. from a particular altitude the

model flies such and such a distance. The glide angle increases

as wing loading rises, and at the same time - of course - the

model’s airspeed increases. This becomes necessary if you wish

to fly in relatively strong winds, and when you need “energy

retention” for flying aerobatics.

For thermal flying you need a good glide angle too, as this is the

key to flying across areas of “sink” (the opposite of a thermal)

quickly, so that you can seek out another thermal. To increase

the glide angle you need to increase the wing loading, and this is

done by increasing the glider’s weight, i.e. by installing ballast in

the model. This should be positioned in the wing if possible. In

the EasyGlider PRO there is an ideal location: it is the GRP tube

which forms the wing joiner. The internal diameter of this tube is

7.8 mm. Normally a ballast rod of this size would be difficult to

find, and expensive to purchase. However, by chance the diameter

of standard M8 studding (threaded rod) is just the right size. This

material has a diameter of 7.7 mm, and you will be able to

buy it at low cost in any DIY store. You may find that only half a

full length is sufficient. In this case you must ensure that the rod

cannot slide from side to side, e.g. by fitting lengths of balsa dowel

in both ends of the wing joiner, so that the weight is held in the

centre.

Safety

Safety is the First Commandment when flying any model aircraft.

Third party insurance should be considered a basic essential. If

you join a model club suitable cover will usually be available

through the organisation. It is your personal responsibility to ensure

that your insurance is adequate.

Make it your job to keep your models and your radio control system

in perfect order at all times. Check the correct charging procedure

for the batteries used in your RC set. Make use of all sensible

safety measures and precautions which are advised for your

system. An excellent source of practical accessories is the MUL-

TIPLEX main catalogue, as our products are designed and

manufactured exclusively by practising modellers for other

practising modellers.

Always fly with a responsible attitude. You may think that flying

low over other people’s heads is proof of your piloting skill; others

know better. The real expert does not need to prove himself in

such childish ways. Let other pilots know that this is what you

think too. Always fly in such a way that you do not endanger

yourself or others. Bear in mind that even the best RC system in

the world is subject to outside interference. No matter how many

years of accident-free flying you have under your belt, you have

no idea what will happen in the next minute.

The fascination of it all

Model flying is, and always has been, a fascinating hobby, and a

thoroughly enjoyable way of spending your leisure hours. Take

your time to get to know your new EasyGlider PRO really well.

Plan to spend many hours in the open air, where you will learn to

appreciate the model’s excellent performance and its docile

handling. You can join us in enjoying one of the few types of sport

which combine high technology, manual dexterity, and

sophisticated personal skills. You can fly alone or with friends,

and at the same time you can enjoy the pleasures of nature -

treats which have become rare in today’s world.

We - the MULTIPLEX team - wish you many hours of pleasure in

building and flying your new model. Happy landings!

Wing section

The wing features a cambered airfoil section over which the air

flows when the model is flying. In a given period of time the air

flowing over the top surface of the wing has to cover a greater

distance than the air flowing under it. This causes a reduction in

pressure on the top surface, which in turn creates a lifting force

which keeps the aircraft in the air. Fig. A

Centre of Gravity (CG)

To achieve stable flying characteristics your model aircraft must

balance at a particular point, just like any other aircraft. It is

absolutely essential to check and set the correct CG position

before flying the model for the first time.

The CG position is stated as a distance which is measured aft

from the wing root leading edge, i.e. close to the fuselage. Sup-

port the model at this point on two fingertips (or - better - use the

MPX CG gauge, # 69 3054); the model should now hang level.

Fig. B

If the model does not balance level, the installed components

(e.g. flight battery) can be re-positioned inside the fuselage. If

this is still not sufficient, attach the appropriate quantity of trim

ballast (lead or plasticene) to the fuselage nose or tail and secure

it carefully. If the model is tail-heavy, fix the ballast at the fuselage

nose; if the model is tail-heavy, attach the ballast at the tail end of

the fuselage.

The longitudinal dihedral is the difference in degrees between

the angle of incidence of the wing and of the tail. Provided that

you work carefully and attach the wing and tailplane to the fuselage

without gaps, the longitudinal dihedral will be correct automatically.

If you are sure that both these settings (CG and longitudinal

dihedral) are correct, you can be confident that there will be no

major problems when you test-fly the model. Fig. C

Control surfaces, control surface travels

The model will only fly safely, reliably and accurately if the control

surfaces move freely and smoothly, follow the stick movements

in the correct “sense”, and move to the stated maximum travels.

The travels stated in these instructions have been established

during the test-flying programme, and we strongly recommend

that you keep to them initially. You can always adjust them to

meet your personal preferences later on.

Transmitter controls

The transmitter features two main sticks which the pilot moves to

control the servos in the model, which in turn operate the control

surfaces.

The functions are assigned according to Mode A, although other

stick modes are possible.

The transmitter controls the control surfaces as follows:

Rudder (left / right) Fig. D

Elevator (up / down) Fig. E

Aileron (left / right) Fig. F

Throttle (motor off / on) Fig. G

Unlike the other controls, the throttle stick must not return to the

neutral position automatically. Instead it features a ratchet so that

it stays wherever you put it. Please read the instructions supplied

with your radio control system for the method of setting up and

adjusting the transmitter and receiving system.

Basic information relating to model aircraft

Any aircraft, whether full-size or model, can be controlled around the three primary axes: vertical (yaw), lateral (pitch) and longitudinal

(roll).

When you operate the elevator, the model’s attitude alters around the lateral axis. If you apply a rudder command, the model swings

around the vertical axis. If you move the aileron stick, the model rolls around its longitudinal axis. External influences such as air

turbulence may cause the model to deviate from its intended flight path, and when this happens the pilot must control the model in

such a way that it returns to the required direction. The basic method of controlling the model’s height (altitude) is to vary motor speed

(motor and propeller). The rotational speed of the motor is usually altered by means of a speed controller. Applying up-elevator also

causes the model to gain height, but at the same time it loses speed, and this can only be continued until the model reaches its

minimum airspeed and stalls. The maximum climb angle varies according to the power available from the motor.
